Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

Please answer my question

The variation of pump head, efficiency, and required ENPY parameters with flow rate obtained from the pump
manufacturer for the pump considered to be used in the following pumping system is given in the table below. The
pump is required to pump from the subaqueous tank to the upper tank at a rate of 6500 lt/min at 40 °C. The diameter
of the suction pipe is 16 cm and the discharge pipe is 8 cm, the length of the suction pipe is 6 m, and the discharge pipe
is 50 m. The roughness value of the pipe is 0.032 mm. The characteristics of the 3 elbows in the system are the same,
and the loss coefficients of the elements causing local loss are given on the figure. The atmospheric pressure at the
location where the pump is installed is 101325 Pa. The variation of the pump head, efficiency, and required ENPY at
1450 rpm of a centrifugal pump with a wheel diameter of cm obtained from the pump manufacturer for the pump
considered to be used in the system is given in the table below.
